Q.
Assertion: Following are the members of a homologous series:
$C H_{3} O H, C H_{3} C H_{2} O H, C H_{3} C H_{2} C H_{2} O H$

Reason: A series of compounds with same functional group but differing by $— C H_{2} —$ unit is called a homologous series.

Solution

Q.
Assertion: Following are the members of a homologous series:
$C H_{3} O H, C H_{3} C H_{2} O H, C H_{3} C H_{2} C H_{2} O H$

Reason: A series of compounds with same functional group but differing by $— C H_{2} —$ unit is called a homologous series.

1 Both assertion and reason are correct and reason is the correct explanation of assertion.

2 Both assertion and reason are correct, but reason is not the correct explanation of assertion.

3 Assertion is true, but reason is false.

4 Assertion is false, but reason is true.

Ans.
(1)

The Homologous series of the compounds differ by $— C H_{2}$ units and molecular mass of each member differs by 14 amu.
